FROM THIS EPISODE

With a declining market for coal in the United States, the coal industry wants to export its product to China, where demand is bigger than ever. What would rail traffic and new port construction mean for the environment and the “clean economy” of the Pacific Northwest? What about global warming? Also, protests fan across Egypt on the anniversary of revolt, and the author of a new book is creating a stir about the Church of Scientology.

In Egypt on the second anniversary of the ouster of Hosni Mubarak, Tahrir Square is full of new protesters against his successor, Mohammed Morsi. David Kirkpatrick, Cairo Bureau Chief for the New York Times, has an update.

The US is getting "greener" as coal is replaced by natural gas, which is cleaner and cheaper, but that doesn't mean the coal industry's going away. Its salvation might lie in exports. Massive coal deposits on federal land in Wyoming and Montana have already been leased to companies with plans for export to China. That's created furious opposition to mile-long coal trains and entire new ports proposed for construction on the Pacific coast. What would it mean for local pollution and global warming? Will the principal benefits go to the public or the coal industry?

When L. Ron Hubbard founded Scientology, he hoped to recruit such figures as Walt Disney, Marlene Dietrich and Jackie Gleason. A new book reports on the church and its relationship with Hollywood. Kim Masters, host of KCRW's The Business, recently sat down with Lawrence Wright, a Pulitzer Prize winner whose latest book is Going Clear: Scientology, Hollywood and the Prison of Belief.

(In response to our request for comment, the Church of Scientology sent a four-page letter saying that Wright's book is "riddled with mistakes, unfounded statements and utterly false and unsupportable facts." The complete interview is available at KCRW.com/Scientology, where you can also find a transcript and the full text of the church's letter.)
